It operates from 1.7 V to 3.6 V and includes a full set of peripherals: CANbus, USB OTG, multiple I²C and SPI interfaces, a 16-channel 12-bit ADC, and a 2-channel 12-bit DAC. The 180 MHz core delivers enough throughput for real-time motor control, digital power conversion, and audio processing without needing an external DSP. The 64-LQFP (10x10 mm) package fits medium-density PCB layouts common in industrial drives and IoT gateways. ## Industrial temperature range — deployment context It is not qualified for under-hood automotive use. ## End-of-life — sourcing reality The STM32F446RET6TR is marked end-of-life. No official successor is listed. For existing BOM lines, a last-time-buy or surplus-channel procurement is the path forward. ## Packaging — Cut Tape or full reel The Cut Tape variant lets you buy small quantities for prototyping or low-volume production without committing to a full reel. Store the reels dry — the 64-LQFP is moisture-sensitive and needs a dry cabinet or bake before reflow if the seal is broken.","metaTitle":"ST STM32F446RET6TR ARM Cortex-M4 MCU, 180MHz, 512KB Flash, 64-LQFP","metaDescription":"STMicroelectronics STM32F446RET6TR 32-bit ARM Cortex-M4 MCU. 180MHz core, 512KB Flash, 128KB RAM, 1.7-3.6V supply, 50 GPIO, 64-LQFP.
